10 Professional PCBs for $ 2 with JLCPCB – Ard-LoRa Prototypes

In my last tests I have used platforms like ESP8266 implementing LoRa modulation and in some applications with LoRaWAN, in this opportunity I will use the Arduino platform and I will manufacture a prototype I have contacted again to JLCPCB that they offer a PCB manufacturing service at a very reasonable price. In this opportunity I will use…

Gateway LoRaWan ESP8266 & RFM95 (ESP-LoRa) 915mHz single channel with The Things Network

For a few weeks I have tested with LoRa technology, we have also heard about LoRaWAN, some time later we created an account on the TTN Platform or “The Things Network”, applied especially to these LP-WAN networks, for this new tutorial we will create a gateway LoRaWAN using an ESP8266 module and a Radio Modem RFM95/95W at…

Complete Installation Node-RED in Raspberry Pi

In this opportunity I will realize the installation of Node-RED in my Raspberry Pi, in case you have not heard about Node-RED, it is a tool for programming and connection of applications for the IoT or Internet of things, integrates protocols, API’S, hardware and software, has a web IDE for connection of nodes in flow mode.    …

Meter PZEM-004T with Arduino ESP32 ESP8266 Python & Raspberry Pi

In this opportunity we will collect tests with my new electric consumption meter PZEM-004T, making integrations with some of the most known hardware platforms ESP8266, Arduino Nano, ESP32, Arduino UNO + Shield Ethernet W5100 and Python in Raspberry Pi. For a long time I wanted to try the PZEM-004T of Peacefair, I bought my meter…

Meter PZEM-004 + ESP8266 & Platform IoT Ubidots

In this opportunity we will integrate our active power meter or power consumption, Peacefair Pzem-004 with the IoT Ubidots platform using an ESP8266 module, later we will create a dashboard to visualize the 4 available variables such as active power, accumulated electrical consumption, voltage and current . Update Ubidots Libraries V3.0.0 for ESP8266 modules I…

Alexa Amazon Echo Dot First Steps and Settings

For a long time I wanted to try one of these Amazon Echo and a few weeks ago mine arrived, but what is it and what can be done with them? let’s configure and test a little. Amazon Echo is a smart speaker with additional functions such as the ability to send voice commands, ask…

Comparison Measurements Peacefair Power PZEM 004 VS Chint DDS666 & ESP8266

We have previously performed tests with 2 active power meters. In this case we will visualize the difference of both measures of instantaneous active power. I notice that I do not have a standard meter to take as a reference, I simply want to corroborate that if the calculation made in Arduino IDE with the…

10 PCB’s Professionals with Seeed Studio Fusion – ESP-LoRa Prototypes

A few days ago I finished tests on my breadboard, being positive I decided to migrate my project to a pcb not only for functionality and practicality, but also for aesthetics, I have chosen the PCB manufacturer company Seeedstudio.com, we all know it as a manufacturer of hardware and IoT solutions , but they also have…

Introduction and Create account in Platform The Things Network IoT LoRaWAN

In this opportunity we will create an account in the platform The Things Network and we will make a brief introduction, TTN a good initiative to build a network for the internet of things or “IoT”. The Things Network has implemented the LoRaWAN technology, which has 3 important characteristics LoRaWAN is technically a standard protocol…
